Optical Methods in Solid and Fluid Mechanics

Engineers and researchers often need to measure physical quantities in solids and fluids without disturbing the systems themselves. Optical measurement techniques provide non-contact, high-precision solutions to capture complex stress fields and fluid flows in real time. This course guides you through the foundational physics and practical applications of these powerful diagnostic tools. You will transition from understanding how light interacts with different media to analyzing real-world mechanical behaviors. By studying the written explanations and mathematical formulations, you will learn how to select and apply the right optical methods for diverse engineering challenges. What you'll learn: - Understand the fundamental wave optics principles behind interferometry, photoelasticity, and digital image correlation - Analyze stress and strain distributions in solid structures using non-contact optical techniques - Measure fluid velocity profiles and flow patterns using particle image velocimetry and schlieren imaging - Configure optical setups by choosing appropriate light sources, lenses, and sensors for specific measurement goals - Practice interpreting raw optical data and fringe patterns to extract quantitative physical measurements - Explore modern digital image processing concepts used to automate and refine optical data analysis The course begins with essential wave optics terminology and core mathematical foundations before guiding you step-by-step through specific solid and fluid measurement techniques. You will explore detailed written case studies and step-by-step analytical procedures that show how these methods are applied in modern research and industrial testing. This course is designed for undergraduate students, graduate researchers, and practicing engineers in mechanical, aerospace, civil, or chemical engineering who are new to optical diagnostics.
